How to make individual rainbow cake layers?

[LoveSewingBee]

I would like to make a rainbow cake. But if I would like to bake each layer separately it would tkae ages before all layers have been baked (i have only one tin in a given size). Could I use my tin and put baking paper between layers to keep them separare whilst baking them all at on e or would this not work?

Bee, i found an interesting way on youtube how to make a rainbow cake using one tin, the first colour went in then straight on top they put the other colour, and so on , it didnt run or anything i was abit dubious when i saw it but it turned out fine.

Oh no this is unbaked, but i think they used a Betty Crocker white cake mix cos i'm sure they used oil.
